BBANDING.

Application filed August 21, 1922. Serial No. 583,418.

My invention relates to branding tubes and the principal object of my invention is to provide anew and improved method of and means for branding all sizes of tubes.

In the drawings accompanying this specification and forming a part thereof I have shown, for purposes of illustration, one form which my invention may assume. In these drawings Figure 1' is a perspective view of this illustrative embodiment.

Figure 2 is across-sectional View showing the tube mounted upon a mandrel in position'to be stamped, while Figure 3 is a cross-sectional view of the tube mounted on a mandrel showing'the tube flattened during the stamping thereof.

The device herein shown comprises a stand 11 carrying a bar 12 adapted to sup- 20 port one end 13 of a mandrel 1d the other end 15 of which is adapted to receive the tube 16 and rest upon any suitable support such as the table 17.

ports a plate 18 provided with a plurality i of holes 19 adapted to receive'and support,

the idle mandrels 20. v V

In use the operator selects a mandreljwhose diameter is properly smaller than the inside mg placing the tube upon a bar of such size diameter of the tube, inserts the end 13 of the, mandrel 1 1 between the uprights 23 and;

underthe bar 12 so that the bar will become lodged in the groove 24 to support that end of the mandrel, and then rests the other end upon the support 17. For each tubeto be branded the operator raises the end 15 of the mandrel 1 1, places the tube 16 on the mandrel, replaces the mandrel on the table, and then presses the stamp 21 against the The stand 11 also sup tube 16 at 22. Due to therigidity ofthe tube the stamp 21 will flatten the tube at that point to form a flat stamping surface trative only and my invention is not limited thereto.

I claim: I v 1. The method of branding tubes comprising placing the tube upon a somewhat smaller mandrel, placing said mandrel and the' tube upon a'support to form a cavity between the upper part of the mandrel and the tube, and pressing a stamp against the tubeto form a flat surface while stamping.

2. The method of branding tubes comprising placing the tube upon a bar of such size and shape as to form a cavity between saidbar and the tube, removably supporting the bar at one end With the tube thereon and resting the other end. upon a support, and pressing a stamp against the tube where the cavity has been formed to form a fiat surface While stamping.

3. The method of branding tubes comprisand shape as to form a cavity between said bar and the tube when the latter is placed upon a supporting surface and pressing a stamp against the tube at that point to form a flat-surface while stamping.

In testimony whereof I have signed my name to the above specification.
